Answer:

Final: 0.234375

3/8 for purple

5/8 for orange

Step-by-step explanation:

Add the 3p and 5o to get a total of 8 jelly beans

Probability of Purple- 3/8:because 3 out of the eight jelly beans are purple

Probability of Orange-5/8: because 5 of the eight jelly beans are orange

The following was solved by someone else

Multiply- 3/8×5/8

WILL GIVE BRAINLIEST! Someone please graph these, I can't graph them.
nadezda [96]

Answer:

see attached image

Step-by-step explanation:

F(x) = 2x + 5 is a linear graph because the exponent on x is 1.  I tell my students that think of graphs having one less turn/corner that the value of the highest exponent.  so since 2x has a exponent of 1, 1-1 =0 so it has no turns or its a straight line.

this has a slope of 2 or 2/1 or up 2 and right 1 from the y intercept which is 5

so mark 5 on the y axis and a from there go up 2 and right 1 and make another point.  Join these points and you have your graph


and


g(x) = (x-5)/2  is its inverse and is found:

F(x) = 2x + 5 write it this way y = 2x + 5

now swap the x and y    x = 2y - 5

solve for y

x = 2y + 5

- 5       -5

x - 5 = 2y

/2        /2

(x-5)/2 = y

it can be written as y = x/2 - 5/2

and graphed the same way as above with a  1/2 slope and -5/2 y intercept

Find three consecutive odd integers such that
Anuta_ua [19.1K]

Answer:

17, 19, 21

Step-by-step explanation:

x = first number

x+2 = second number

x+4 = third number

4x + 3(x+2) + 2(x+4) = 167

simplify:

4x + 3x + 6 + 2x + 8 = 167

combine like terms:

9x + 14 = 167

subtract 14 from each side of the equation:

9x = 153

divide both sides by 9:

x = 17

Find the inverse function
Troyanec [42]

The inverse of the function is f(x) = x^{3} + 8

In order to find the inverse of any function, start by switching the f(x) and x. Then solve for the new f(x). The result will be the inverse function. The work is below for you.

f(x) = \sqrt[3]{x - 8} ----> Switch f(x) and x

x = \sqrt[3]{f(x) - 8} ----> Cube both sides

x^{3} = f(x) - 8 ----> Add 8 to both sides

f(x) = x^{3} + 8

How do you convert a ratio from length to volume? *
n200080 [17]

Answer:

Notice that for any increase, x * l or x * r, in length or radius, the increase in surface area is x squared (x2) and the increase in volume is x cubed (x3).
